User Manual

Failure to adhere to these warnings will void your warranty and destroy your flight
controller.
• Observe polarity at ALL TIMES. Check and DOUBLE CHECK before applying pow-
er.
• POWER OFF before unplugging, plugging in or making any connections.
• Connect only one 5.0v SOURCE of power to the VCC pins / Do not connect more
than one source of power to two or more of the VCC pins. e.g. If you are using
ESCs with BECs then remove the center RED wire from all but one ESC connector.
• Do not connect GND, VCC or 3.3v to each other (short circuit).
• Do not connect GND, VCC or 3.3v to any inputs or outputs unless specifically stat-
ed.
• Do not connect any input or output to any other input or output unless specifically
stated.
• The 3.3v supply is for low-current use only. 100mA MAX.
• Do not allow dirt/dust/glue/etc into the pressure sensor (barometer).
• Keep magnets away from the flight controller.
• Do not use a voltage source higher than 5.0v. Check your 5v suppy is actually
outputting 5.0 volts, check it before powering the FC - do not just assume it is 5v.
• Do not connect a LiPo to the 5.0v VCC pins.
WARNINGS
GENERAL ADVICE
Follow the advice below for best performance and long-life of your flight controller:
• Apply resin/glue to reinforce JST-SH connectors - helps if you crash your aircraft.
• To further protect the board from crashes you can add a some additional solder to
the edges of the JST-SH and USB sockets to reinforce them.
• Using an enclosure/box for the flight-controller is recommended.
• Install open-cell foam under the pressure sensor - sandwich some between the FC
and frame.
• Route motor/battery wires as far away from the compass sensor (magnetometer)
as possible.
• Only install the BOOT jumper pins if you need them.
• Using color coded pin headers is recommended (not supplied), especially for VBAT
headers.
• Do everything you can to prevent vibrations reaching the accelerometer/gyro sen-
sor. e.g. balance props, motors and secure everything.
